The aim of present study is to examine the infleunce of mode of
delivery on the neonatal thyroid hormones immediately after birth by
comparing serum concentrations of these hormones in neonates delivered
by normal vaginal deliveries and those by caesarean sections. This study
included three groups of newborns from uncomplicated pregnancies:
Group (I) included 20 newborns delivered by normal vaginal deliveries
(N.V.D), Group (II) included 20 newborns delivered by emergency
caesarean sections (EMCS) and group (III) included 20 newborns
delivered by elective caesarean sections (ELCS). Umbilical venous blood
samples were obtained immediately after birth. Serum T3, T4, TSH,
glucose and free fatty acids (FFA) were measured. There were significant
increases (P<0.05) in serum T3, T4 and TSH in newborns delivered by
EMCS and ELCS compared to neonates delivered by normal vaginal
deliveries (NVD) and also, serum T3, T4 and TSH were significantly
increased (p<0.05) in newborns delivered by ELCS compared to those
delivered by EMCS. We concluded that the mode of delivery affect the
serum concentrations of thyroid hormones and TSH at birth. |
